### Describe the Bug The PlatformIO Extension is not available in Cursor IDE (but is available in VSCODE) ### Steps to Reproduce Open cursor extensions and type PlatformIO ### Expected Behavior PlatformIO should be available in the search results ### Operating System Linux ### Current Cursor Version (Menu → About Cursor → Copy) Version: 1.2.4 VSCode Version: 1.99.3 Commit: a8e95743c5268be73767c46944a71f4465d05c90 Date: 2025-07-10T16:59:43.242Z Electron: 34.5.1 Chromium: 132.0.6834.210 Node.js: 20.19.0 V8: 13.2.152.41-electron.0 OS: Linux x64 6.6.99-1-MANJARO ### Additional Information I am able to manually install the extension from a vsix file exported from VsCode if I also manually install vscode C/C++ support. The C/C++ extension complains that it will only work on Microsoft branded vscode installations, so it may simply be a matter of allowing platformIO to depend on the Anysphere C/C++ extension. P.S. Cursor is AWESOME on ESP32 projects! PlatformIO support is essential to make it work. ### Does this stop you from using Cursor No - Cursor works, but with this issue ---

hi @Prismo and thank you for the detailed report. As Cursor is using the OpenVSX marketplace for extensions could you contact the extension developer to also submit it there? It would allow then all users to install it from the marketplace. Kindly note that we are not managing the Marketplace so only the developer can submit it there. ---

Thanks @condor. Understood, thanks for explaining. I’ll follow up with the extension developer. ---

hi @condor it looks like the platformIO extension relies on ms-vscode.cpptools which is not in OpenVSX I have hacked my installation of platformIO to rely on anysphere.cpptools instead and it seems to work. I would like to suggest this as a fix to the extension developer however I am unable to find a license for anysphere.cpptools, or a listing for it in OpenVSX. Could you shed some light on where this information might be found? ---

Platformio is not published on OpenVSX, but their code is open source: [platformio/platformio-vscode-ide](https://github.com/platformio/platformio-vscode-ide). If you’d like to take this on, you can modify the extension to remove the hard dependency on MS cpptools and submit the modified version to OpenVSX. ---

Thanks for the reply @ravirahman . I can’t find **anysphere.cpptools** listed on the OpenVSX registry: [Open VSX Registry](https://open-vsx.org/?search=anysphere.cpptools&sortBy=relevance&sortOrder=desc) Is **anysphere.cpptools** extension available on OpenVSX? ---

No, `anysphere.cpptools` is not published on OpenVSX. I’d recommended listing it as part of the `extensionPack` (optional) dependencies in the package.json, or simply depending on clangd (`llvm-vs-code-extensions.vscode-clangd`). ---

Hey everyone, can you please try this in Cursor? [https://open-vsx.org/extension/DavidGomes/platformio-ide](https://open-vsx.org/extension/DavidGomes/platformio-ide) I have been able to get this to work on my local Cursor for any PlatformIO project. What I did was: - Make this require the Clang CPP extension (so you should get a notification to install it if you haven’t already, and this extension won’t even load until you do that) - For every PlatformIO project, the extension now generates a `compile_commands.json` file in the project directory so that the Clang CPP extension works properly ---
